FIELD

The discovery is in the field of sorghum (Sorghum bicolor L. Moench)breeding, specifically relating to the sorghum line designatedPHO17QMIT.

BACKGROUND

The goal of plant breeding is to combine in a single variety variousdesirable traits. For field crops, these traits may include higher seedyield, higher biomass yield, higher sugar yield, improved compositiontraits, improved conversion traits, resistance to diseases and insects,better stems and roots, tolerance to heat, tolerance to lowtemperatures, tolerance to drought and salt, reducing the time to cropmaturity, greater yield and yield stability, presence or absence ofdwarfing genes, improved nutrient value, increased growth rate, andbetter agronomic characteristics or grain quality. With mechanicalharvesting of many crops, uniformity of plant characteristics such asgermination and stand establishment, growth rate, maturity, plant heightand fruit size, is important.

Grain sorghum is an important and valuable food and feed grain crop. Inaddition, its vegetative parts are used for forage, syrup and shelter.Thus, a continuing goal of plant breeders is to develop stable highyielding sorghum hybrids that are agronomically sound. The reasons forthis goal are to maximize the amount of grain produced on the land usedand to supply food for both animals and humans.

Sorghum is in the same family as maize and has a similar growth habit,but with more tillers and a more extensively branched root system.Sorghum is more drought resistant and heat-tolerant than maize. Itrequires an average temperature of at least 25° C. to produce maximumyields. Sorghum's ability to thrive with less water than maize may bedue to its ability to hold water in its foliage better than maize.Sorghum has a waxy coating on its leaves and stems which helps to keepwater in the plant even in intense heat. Wild species of sorghum tend togrow to a height of 1.5 to 2 meters; however in order to improveharvestability, dwarfing genes have been selected in cultivatedvarieties and hybrids such that most cultivated varieties and hybridsgrow to between 60 and 120 cm tall.

DETAILED DESCRIPTION

Field crops are bred through techniques that take advantage of theplant's method of pollination. A plant is self-pollinating if pollenfrom one flower is transferred to the same or another flower of the sameplant. A plant is cross-pollinated if the pollen comes from a flower ona different plant.

Plants that have been self-pollinated and selected for type for manygenerations become homozygous at almost all gene loci and produce auniform population of true breeding progeny. A cross between twohomozygous plants from differing backgrounds or two homozygous linesproduce a uniform population of hybrid plants that may be heterozygousfor many gene loci. A cross of two plants that are each heterozygous ata number of gene loci will produce a population of hybrid plants thatdiffer genetically and will not be uniform.

Sorghum plants (Sorghum bicolor L. Moench) are bred in most cases byself pollination techniques. With the incorporation of male sterility(either genetic or cytoplasmic) cross pollination breeding techniquescan also be utilized. Sorghum has a perfect flower with both male andfemale parts in the same flower located in the panicle. The flowers areusually in pairs on the panicle branches. Natural pollination occurs insorghum when anthers (male flowers) open and pollen falls onto receptivestigma (female flowers). Because of the close proximity of male(anthers) and female (stigma) in the panicle, self pollination is veryhigh (average 94%). Cross pollination may occur when wind or convectioncurrents move pollen from the anthers of one plant to receptive stigmaon another plant. Cross pollination is greatly enhanced withincorporation of male sterility which renders male flowers nonviablewithout affecting the female flowers. Successful pollination in the caseof male sterile flowers requires cross pollination.

Inbred Development

The development of sorghum hybrids requires the development ofhomozygous inbred lines, the crossing of these lines, and the evaluationof the crosses. Pedigree breeding methods, and to a lesser extentpopulation breeding methods, are used to develop inbred lines frombreeding populations. Breeding programs combine desirable traits fromtwo or more inbred lines into breeding pools from which new inbred linesare developed by selfing and selection of desired phenotypes. The newinbreds are crossed with other inbred lines and the hybrids from thesecrosses are evaluated to determine which have commercial potential.

Pedigree breeding starts with the crossing of two genotypes, each ofwhich may have one or more desirable characteristics that is lacking inthe other or which complement the other. If the two original parents donot provide all of the desired characteristics, other sources can beincluded in the breeding population. In the pedigree method, superiorplants are selfed and selected in successive generations. In thesucceeding generations the heterozygous condition gives way tohomogeneous lines as a result of self-pollination and selection.Typically, in the pedigree method of breeding five or more generationsof selfing and selection is practiced. F₁ to F₂; F₂ to F₃; F₃ to F₄, F₄to F₅, etc.

Backcrossing can be used to improve an inbred line. Backcrossingtransfers a specific desirable trait from one inbred or source to aninbred that lacks that trait. This can be accomplished for example byfirst crossing a superior inbred (A) (recurrent parent) to a donorinbred (non-recurrent parent), which carries the appropriate genes(s)for the trait in question. The progeny of this cross is then mated backto the superior recurrent parent (A) followed by selection in theresultant progeny for the desired trait to be transferred from thenon-recurrent parent. After five or more backcross generations withselection for the desired trait, the progeny will be heterozygous forloci controlling the characteristic being transferred, but will be likethe superior parent for most or almost all other genes. The lastbackcross generation would be selfed to give pure breeding progeny forthe gene(s) being transferred.

Controlling Self-Pollination

Sorghum varieties are mainly self-pollinated; therefore,self-pollination of the parental varieties must be controlled to makehybrid development feasible. A pollination control system and effectivetransfer of pollen from one parent to the other offers improved plantbreeding and an effective method for producing hybrid seed and plants.For example, the milo or A₁ cytoplasmic male sterility (CMS) system,developed via a cross between milo and kafir cultivars, is one of themost frequently used CMS systems in hybrid sorghum production (StephensJ C & Holland P F, Cytoplasmic Male Sterility for Hybrid Sorghum SeedProduction, Agron. J. 46:20-23 (1954)). Other CMS systems for sorghuminclude, but are not limited to, A₂, isolated from IS 12662c (Schertz KF, Registration of A ₂ T _(x) 2753 and BT _(x) 2753 Sorghum Germplasm,Crop Sci. 17: 983 (1977)), A₃, isolated from IS 1112c or converted Nilwa(Quinby J R, Interactions of Genes and Cytoplasms in Male-Sterility inSorghums, Proc. 35th Corn Sorghum Res. Conf. Am. Seed Trade Assoc.Chicago, Ill., pp. 5-8 (1980)), A₄, isolated from IS 7920c (Worstell etal, Relationship among Male-Sterility Inducing Cytoplasms of Sorghum,Crop Sci. 24:186-189 (1984)).

In developing improved new sorghum hybrid varieties, breeders may use aCMS plant as the female parent. In using these plants, breeders attemptto improve the efficiency of seed production and the quality of the F₁hybrids and to reduce the breeding costs. When hybridization isconducted without using CMS plants, it is more difficult to obtain andisolate the desired traits in the progeny (F₁ generation) because theparents are capable of undergoing both cross-pollination andself-pollination. If one of the parents is a CMS plant that is incapableof producing pollen, only cross pollination will occur. By eliminatingthe pollen of one parental variety in a cross, a plant breeder isassured of obtaining hybrid seed of uniform quality, provided that theparents are of uniform quality and the breeder conducts a single cross.

In one instance, production of F₁ hybrids includes crossing a CMS femaleparent with a pollen-producing male parent. To reproduce effectively,however, the male parent of the F₁ hybrid must have a fertility restorergene (Rf gene). The presence of an Rf gene means that the F₁ generationwill not be completely or partially sterile, so that eitherself-pollination or cross pollination may occur. Self pollination of theF₁ generation to produce several subsequent generations is important toensure that a desired trait is heritable and stable and that a newvariety has been isolated.

Promising advanced breeding lines commonly are tested and compared toappropriate standards in environments representative of the commercialtarget area(s). The best lines are candidates for new commercial lines;and those still deficient in a few traits may be used as parents toproduce new populations for further selection.

Hybrid Development

A hybrid sorghum variety is the cross of two inbred lines, each of whichmay have one or more desirable characteristics lacked by the other orwhich complement the other. The hybrid progeny of the first generationis designated F₁. In the development of hybrids only the F₁ hybridplants are sought. The F₁ hybrid is more vigorous than its inbredparents. This hybrid vigor, or heterosis, can be manifested in manyways, including increased vegetative growth and increased yield.

The development of a hybrid sorghum variety involves five steps: (1) theformation of “restorer” and “non-restorer” germplasm pools; (2) theselection of superior plants from various “restorer” and “non-restorer”germplasm pools; (3) the selfing of the superior plants for severalgenerations to produce a series of inbred lines, which althoughdifferent from each other, each breed true and are highly uniform; (4)the conversion of inbred lines classified as non-restorers tocytoplasmic male sterile (CMS) forms, and (5) crossing the selectedcytoplasmic male sterile (CMS) inbred lines with selected fertile inbredlines (restorer lines) to produce the hybrid progeny (F₁).

Because sorghum is normally a self pollinated plant and because bothmale and female flowers are in the same panicle, large numbers of hybridseed can only be produced by using cytoplasmic male sterile (CMS)inbreds. Flowers of the CMS inbred are fertilized with pollen from amale fertile inbred carrying genes which restore male fertility in thehybrid (F₁) plants. An important consequence of the homozygosity andhomogeneity of the inbred lines is that the hybrid between any twoinbreds will always be the same. Once the inbreds that produce the besthybrid have been identified, the hybrid seed can be reproducedindefinitely as long as the homogeneity of the inbred parent ismaintained.

A single cross hybrid is produced when two inbred lines are crossed toproduce the F₁ progeny. Much of the hybrid vigor exhibited by F₁ hybridsis lost in the next generation (F₂). Consequently, seed from hybridvarieties is not used for planting stock.

Hybrid grain sorghum can be produced using wind to move the pollen.Alternating strips of the cytoplasmic male sterile inbred (female) andthe male fertile inbred (male) are planted in the same field. Wind movesthe pollen shed by the male inbred to receptive stigma on the female.Providing that there is sufficient isolation from sources of foreignsorghum pollen, the stigma of the male sterile inbred (female) will befertilized only with pollen from the male fertile inbred (male). Theresulting seed, born on the male sterile (female) plants is thereforehybrid and will form hybrid plants that have full fertility restored.

Locus Conversions of Sorghum Line PHO17QMIT

PHO17QMIT represents a new base genetic line into which a new locus ortrait may be introduced. Direct transformation and backcrossingrepresent two important methods that can be used to accomplish such anintrogression. The term locus conversion is used to designate theproduct of such an introgression.

To select and develop a superior hybrid, it is necessary to identify andselect genetically unique individuals that occur in a segregatingpopulation. The segregating population is the result of a combination ofcrossover events plus the independent assortment of specificcombinations of alleles at many gene loci that results in specific andunique genotypes. Once such a variety is developed its value to societyis substantial since it is important to advance the germplasm base as awhole in order to maintain or improve traits such as yield, diseaseresistance, pest resistance and plant performance in extreme weatherconditions. Locus conversions are routinely used to add or modify one ora few traits of such a line and this further enhances its value andusefulness to society.

Backcrossing can be used to improve inbred varieties and a hybridvariety which is made using those inbreds. Backcrossing can be used totransfer a specific desirable trait from one variety, the donor parent,to an inbred called the recurrent parent which has overall goodagronomic characteristics yet that lacks the desirable trait. Thistransfer of the desirable trait into an inbred with overall goodagronomic characteristics can be accomplished by first crossing arecurrent parent to a donor parent (non-recurrent parent). The progenyof this cross is then mated back to the recurrent parent followed byselection in the resultant progeny for the desired trait to betransferred from the non-recurrent parent.

Traits may be used by those of ordinary skill in the art to characterizeprogeny. Traits are commonly evaluated at a significance level, such asa 1%, 5% or 10% significance level, when measured in plants grown in thesame environmental conditions. For example, a locus conversion ofPHO17QMIT may be characterized as having essentially the same phenotypictraits as PHO17QMIT. The traits used for comparison may be those traitsshown in Table 1. Molecular markers can also be used during the breedingprocess for the selection of qualitative traits. For example, markerscan be used to select plants that contain the alleles of interest duringa backcrossing breeding program. The markers can also be used to selectfor the genome of the recurrent parent and against the genome of thedonor parent. Using this procedure can minimize the amount of genomefrom the donor parent that remains in the selected plants.

A locus conversion of PHO17QMIT will retain the genetic integrity ofPHO17QMIT. A locus conversion of PHO17QMIT will comprise at least 92%,93%, 94%, 95%, 96%, 97%, 98% or 99% of the base genetics of PHO17QMIT.For example, a locus conversion of PHO17QMIT can be developed when DNAsequences are introduced through backcrossing (Hallauer et al., 1988),with a parent of PHO17QMIT utilized as the recurrent parent. Bothnaturally occurring and transgenic DNA sequences may be introducedthrough backcrossing techniques. A backcross conversion may produce aplant with a locus conversion in at least one or more backcrosses,including at least 2 crosses, at least 3 crosses, at least 4 crosses, atleast 5 crosses and the like. Molecular marker assisted breeding orselection may be utilized to reduce the number of backcrosses necessaryto achieve the backcross conversion. For example, see Openshaw, S. J. etal., Marker-assisted Selection in Backcross Breeding. In: ProceedingsSymposium of the Analysis of Molecular Data, August 1994, Crop ScienceSociety of America, Corvallis, Oreg., where it is demonstrated that abackcross conversion can be made in as few as two backcrosses. A locusconversion of PHO17QMIT can be determined through the use of a molecularprofile. A locus conversion of PHO17QMIT would have 92%, 93%, 94%, 95%,96%, 97%, 98% or 99% of the molecular markers, or molecular profile, ofPHO17QMIT. Examples of molecular markers that could be used to determinethe molecular profile include Restriction Fragment Length Polymorphisms(RFLP), Polymerase Chain Reaction (PCR) analysis, and Simple SequenceRepeats (SSR), and Single Nucleotide Polymorphisms (SNPs).

Transformation of Sorghum Line PHO17QMIT

The advent of new molecular biological techniques has allowed theisolation and characterization of genetic elements with specificfunctions, such as encoding specific protein products. Scientists in thefield of plant biology developed a strong interest in engineering thegenome of plants to contain and express foreign genetic elements, oradditional, or modified versions of native or endogenous geneticelements in order to alter the traits of a plant in a specific manner.Any DNA sequences, whether from a different species or from the samespecies, that are inserted into the genome using transformation arereferred to herein collectively as “transgenes.”

Numerous methods for plant transformation have been developed, includingbiological and physical plant transformation protocols. See, forexample, Miki, et al., “Procedures for Introducing Foreign DNA intoPlants” in Methods in Plant Molecular Biology and Biotechnology, Glick.In addition, expression vectors and in vitro culture methods for plantcell or tissue transformation and regeneration of plants are available.See, for example, Gruber, et al., “Vectors for Plant Transformation” inMethods in Plant Molecular Biology and Biotechnology, Glick andThompson, Eds. (CRC Press, Inc., Boca Raton, 1993) pages 89-119.

The most prevalent types of plant transformation involve theconstruction of an expression vector. Such a vector comprises a DNAsequence that contains a gene under the control of or operatively linkedto a regulatory element, for example a promoter. The vector may containone or more genes and one or more regulatory elements.

A genetic trait which has been engineered into a particular sorghumplant using transformation techniques, could be moved into another lineusing traditional breeding techniques that are well known in the plantbreeding arts. For example, a backcrossing approach could be used tomove a transgene from a transformed sorghum plant to an elite inbredline and the resulting progeny would comprise a transgene. Also, if aninbred line was used for the transformation then the transgenic plantscould be crossed to a different line in order to produce a transgenichybrid sorghum plant. As used herein, “crossing” can refer to a simple Xby Y cross, or the process of backcrossing, depending on the context.Various genetic elements can be introduced into the plant genome usingtransformation. These elements include but are not limited to genes;coding sequences; inducible, constitutive, and tissue specificpromoters; enhancing sequences; and signal and targeting sequences. Forexample, see, U.S. Pat. No. 6,118,055.

With transgenic plants according to the present discovery, a foreignprotein can be produced in commercial quantities. Thus, techniques forthe selection and propagation of transformed plants, which are wellunderstood in the art, yield a plurality of transgenic plants which areharvested in a conventional manner, and a foreign protein then can beextracted from a tissue of interest or from total biomass. Proteinextraction from plant biomass can be accomplished by known methods whichare discussed, for example, by Heney and Orr, (1981) Anal. Biochem.114:92-96.

A genetic map can be generated, primarily via conventional RestrictionFragment Length Polymorphisms (RFLP), Polymerase Chain Reaction (PCR)analysis, and Simple Sequence Repeats (SSR), and Single NucleotidePolymorphisms (SNPs), which identifies the approximate chromosomallocation of the integrated DNA molecule coding for the foreign protein.For exemplary methodologies in this regard, see, Glick and Thompson,METHODS IN PLANT MOLECULAR BIOLOGY AND BIOTECHNOLOGY 269-284 (CRC Press,Boca Raton, 1993). Map information concerning chromosomal location isuseful for proprietary protection of a subject transgenic plant. Ifunauthorized propagation is undertaken and crosses made with othergermplasm, the map of the integration region can be compared to similarmaps for suspect plants, to determine if the latter have a commonparentage with the subject plant. Map comparisons would involvehybridizations, RFLP, PCR, SSR, SNP, and sequencing, all of which areconventional techniques.

Likewise, by means of the present discovery, plants can be geneticallyengineered to express various phenotypes of agronomic interest.Exemplary transgenes implicated in this regard include, but are notlimited to, those categorized below.

1. Genes that create a site for site specific DNA integration.

This includes the introduction of FRT sites that may be used in theFLP/FRT system and/or Lox sites that may be used in the Cre/Loxp system.For example, see, Lyznik, et al., (2003) “Site-Specific Recombinationfor Genetic Engineering in Plants”, Plant Cell Rep 21:925-932 and WO99/25821, which are hereby incorporated by reference. Other systems thatmay be used include the Gin recombinase of phage Mu (Maeser, et al.,1991), the Pin recombinase of E. coli (Enomoto, et al., 1983), and theR/RS system of the pSR1 plasmid (Araki, et al., 1992).

2. Genes that affect abiotic stress resistance (including but notlimited to flowering, panicle/glume and seed development, enhancement ofnitrogen utilization efficiency, altered nitrogen responsiveness,drought resistance or tolerance, cold resistance or tolerance, and saltresistance or tolerance) and increased yield under stress.

For example, see, WO 00/73475 where water use efficiency is alteredthrough alteration of malate; U.S. Pat.

3. Transgenes that confer or contribute to an altered graincharacteristic, such as:

-   -   A. Altered phosphorus content, for example, by the        -   (1) Introduction of a phytase-encoding gene would enhance            breakdown of phytate, adding more free phosphate to the            transformed plant. For example, see, Van Hartingsveldt, et            al., Gene 127:87 (1993), for a disclosure of the nucleotide            sequence of an Aspergillus niger phytase gene.        -   (2) Up-regulation of a gene that reduces phytate content. In            maize, this, for example, could be accomplished, by cloning            and then re-introducing DNA associated with one or more of            the alleles, such as the LPA alleles, identified in maize            mutants characterized by low levels of phytic acid, such as            in Raboy, et al. (1990).    -   B. Altered fatty acids, for example, by down-regulation of        stearoyl-ACP desaturase to increase stearic acid content of the        plant. See Knultzon, et al., Proc. Natl. Acad. Sci. USA 89:2624        (1992).    -   C. Altered carbohydrates effected, for example, by altering a        gene for an enzyme that affects the branching pattern of starch,        a gene altering thioredoxin. (See, U.S. Pat. No. 6,531,648).        See, Shiroza, et al., (1988) J. Bacteriol 170:810 (nucleotide        sequence of Streptococcus mutans fructosyltransferase gene),        Steinmetz, et al., (1985) Mol. Gen.

The fatty acid modification genes mentioned above may also be        used to affect starch content and/or composition through the        interrelationship of the starch and oil pathways.    -   D. Altered antioxidant content or composition, such as        alteration of tocopherol or tocotrienols. For example, see, U.S.        Pat. No. 6,787,683, US Patent Application Publication Number        2004/0034886 and WO 00/68393 involving the manipulation of        antioxidant levels through alteration of a phytl prenyl        transferase (ppt), WO 03/082899 through alteration of a        homogentisate geranyl geranyl transferase (hggt).    -   E.

There are several methods of conferring genetic male sterilityavailable, such as multiple mutant genes at separate locations withinthe genome that confer male sterility, as disclosed in U.S. Pat. Nos.4,654,465 and 4,727,219 to Brar, et al., and chromosomal translocationsas described by Patterson in U.S. Pat. Nos. 3,861,709 and 3,710,511. Inaddition to these methods, Albertsen, et al., U.S. Pat. No. 5,432,068,describes a system of nuclear male sterility which includes: identifyinga gene which is critical to male fertility; silencing this native genewhich is critical to male fertility; removing the native promoter fromthe essential male fertility gene and replacing it with an induciblepromoter; inserting this genetically engineered gene back into theplant; and thus creating a plant that is male sterile because theinducible promoter is not “on” resulting in the male fertility gene notbeing transcribed. Fertility is restored by inducing, or turning “on,”the promoter, which in turn allows the gene that confers male fertilityto be transcribed.

Sorghum is used as livestock feed, as sugar or grain for humanconsumption, as biomass, and as raw material in industry. The mostcommon use of sorghum grain in the United States is as livestock feed,primarily to beef cattle, dairy cattle, hogs and poultry. The plant isalso used as livestock feed in the form of fodder, silage, hay andpasture.

Sorghum grain is most important as human food in areas outside theUnited States. In these areas, the grain is consumed in the form ofbread, porridge, confectionaries and as an alcoholic beverage. Grainsorghum may be ground into flour and either used directly or blendedwith wheat or corn flour in the preparation of food products. Inaddition to direct consumption of the grain, sorghum has long been usedin many areas of the world to make beer. The uses of sorghum, inaddition to human consumption of kernels, include both products of dryand wet milling industries. The principal products of sorghum drymilling are grits, meal and flour. Starch and other extracts for fooduse can be provided by the wet milling process.

Sorghum provides a source of industrial raw material. Industrial usesare mainly from sorghum starch from the wet-milling industry and sorghumflour from the dry milling industry. Sorghum starch and flour haveapplication in the paper and textile industries. Other industrial usesinclude applications in adhesives, building materials and as oil-wellmuds. Considerable amounts of sorghum, both grain and plant material,have been used in industrial alcohol production.

Characteristics of PHO17QMIT

Sorghum line PHO17QMIT a grain sorghum inbred parent, was developed byPioneer Hi-Bred International, Inc., from the F₂ population of thesingle cross PHK1WQLI×PHB74GM. Both PHK1WQLI and PHB74GM are proprietarylines of Pioneer Hi-Bred International, Inc.

Sorghum line PHO17QMIT can be used in breeding techniques to createhybrids. PHO17QMIT is a maintainer line that carries a gene for malesterility. When a sterile version of an inbred is pollinated by a maleline that carries a gene for the restoration of fertility, it results ina fertile hybrid. Generally, the seed produced from this cross is theseed that is commercially sold.

To produce sorghum line PHO17QMIT, the pedigree method of breeding wasused. The F₁ cross was made at Manhattan, Kans., during the summer of1997, and F₂ seed was obtained by selfing hybrid plants during thewinter of 1997-1998 in Jamaica, W.I. The F₂ population was grown atManhattan, Kans., during the summer of 1998, and plants wereself-pollinated. Sixty-two heads were selected from the F₂ population.The F₃ family was grown head to row in Manhattan, Kans., during thesummer of 1999. Plants were selfed, and two heads were saved fromselected rows. The F₄ family was grown during the summer of 2000 atManhattan, Kans., where two heads were selfed. Pollen was carried fromselected rows to sterile female lines in A1 cytoplasm to begin thesterilization of the selected lines. The F₅ was grown in Jamaica, W.I.,during the winter of 2000-2001, and two heads were selfed. The F₆ wasgrown in Manhattan, Kans., during the summer of 2001 where two headswere selfed. The F₇ was grown in Puerto Vallarta, MX, during the winterof 2001-2002, and two heads were selfed. In addition, the male sterileA-line version of the line was test crossed to an inbred male testerline for evaluation of combining ability. The F₈ was grown in Manhattan,Kans., during the summer of 2002, and the line was bulked from the bestrow of two. Yield trials were also grown in Manhattan, Kans., involvingthe testcross hybrids made at F₇. Based on yield test results andnursery observation, the line was determined to possess some superiorqualities, and it was selected to advance in the test program. The linewas bulked at F₈.

Sorghum line PHO17QMIT has shown stability for traits listed in Table 1.It has been self-pollinated, bulk increased and checked for uniformityof plant type to assure genetic homozygosity and phenotypic stability.The line has been increased by hand pollination and in isolated fieldplantings with continued observation for uniformity. It has beenobserved to be uniform and stable for at least five generations.

The method of claim 8, further defined as producing aninbred plant derived from sorghum line PHO17QMIT, the method comprisingthe steps of: (a) crossing said first plant with an inducer variety toproduce haploid seed; and (b) doubling the haploid seed to produce aninbred plant derived from sorghum line PHO17QMIT.
 11. A sorghum seedproduced by crossing the plant or non-seed plant part of claim 4 with adifferent plant.
 12. A plant produced by growing the seed of claim 11.13. A method comprising crossing the plant or non-seed plant part ofclaim 1 with another plant or plant part to produce F₁ seed.
 14. The F₁seed of claim
 13. 15. A method comprising growing the seed of claim 14to produce a first plant, and crossing the first plant with itself oranother plant.
 16. The seed, plant, non-seed plant part or cell of claim1, further comprising a cytoplasmic conversion, wherein (i) the seedproduces a plant which has otherwise all of the phenotypic andmorphological characteristics of sorghum variety PHO17QMIT; (ii) theplant has otherwise all of the phenotypic and morphologicalcharacteristics of sorghum variety PHO17QMIT; or (iii) the non-seedplant part or cell produces a plant which has otherwise all of thephenotypic and morphological characteristics of sorghum varietyPHO17QMIT.
 17. The seed, plant, non-seed plant part or cell of claim 16,wherein the cytoplasmic conversion confers the trait of male sterility.18. A method comprising crossing the plant or non-seed plant part ofclaim 17 with another plant to produce F₁ seed.
 19. The F₁ seed producedby the method of claim
 18. 20. A method comprising growing the seed ofclaim 19 to produce a first plant, and crossing the first plant withitself or another plant.
